hundred and forty perfectly annuliform folds. There exists
a small conical tail. The folds of the skin may be easily
raised by a point; and a great number of circular transparent
scales, with a surface relieved by projecting lines, forming a
sort of net. There is a large yellow band on each side of
the body; the submaxillary branches, whose border is

margin of the cloaca, and a small longitudinal stripe upon
the tail.
